Most of them are crying! I’m guessing joy? ;)
When I looked at this picture I thought of the song “What A wonderful world” by Louis Armstrong! I listened to it and looked at this picture and I’m so happy! C:

This pic as a poster in my room and everyday when I woke up I will smile like and retarded hyena.
"Alot of the characters in this picture are crying or just look extremely happy....I'm assuming this is the day they achieve world peace."

Thiiiisssssss (╥﹏╥)

I come close to tears every time I come back to this picture and scrutinize every little bit of it. <3 Germany's serene expression. <3 The only hand Canada's holding in America's. (And their shirts match up, so cute! :3) <3 The family at the end, with Chibitalia and HRE. D'AWWWWH!! X33 And also, how lot's of them seem to be crying with joy. oh my goodness. X) Why can't the world be as peaceful as Hetalia? );

I've seen this picture like, a-hundred time, and I never noticed untill now, but if you look a the patterns and the colors on each countries' shirt, they all look like that counties' flag. Like Japan's go just one red dot in the middle, and America's got red and white strips. Wow, I glad noticed that, makes me feel special, did anyone else notice this aswell??
